7 About this document The Release Notes topics include late technical information that is not included in other topics, and they highlights new functions for the PowerHA SystemMirror Version for Linux licensed program. Highlighting The following highlighting conentions are used in this document: Bold Italics Monospace Identifies commands, subroutines, keywords, files, structures, directories, and other items whose names are predefined by the system. Bold highlighting also identifies graphical objects, such as buttons, labels, and icons that the you select. Identifies parameters for actual names or alues that you supply. Identifies examples of specific data alues, examples of text similar to what you might see displayed, examples of portions of program code similar to what you might write as a programmer, messages from the system, or text that you must type. Case-sensitiity in Linux Eerything in the Linux operating system is case-sensitie, which means that it distinguishes between uppercase and lowercase letters. For example, you can use the ls command to list files. If you type LS, the system responds that the command is not found. Likewise, FILEA, FiLea, and filea are three distinct file names, een if they reside in the same directory. To aoid causing undesirable actions to be performed, always ensure that you use the correct case. ISO 9000 ISO 9000 registered quality systems were used in the deelopment and manufacturing of this product. Copyright IBM Corp. 2017, 2018

8 i IBM PowerHA SystemMirror for Linux Version 7.2.2: Release Notes

9 New functions for PowerHA SystemMirror for Linux Version Serice Pack 1 PowerHA SystemMirror for Linux has the following new functions and updates: SAP HANA and SAP NetWeaer on same cluster PowerHA SystemMirror for Linux can run ABAP Central serices instance (ASCS) and also database (SAP HANA) on same nodes (2 or 3 nodes). SAP NetWeaer and the database serer can be separated into different nodes (4 nodes) when SAP HANA and SAP NetWeaer are running on same cluster. SAP HANA and SAP NetWeaer can be configured in same the cluster, which can create the StartAfter relationship between SAP Application serer resource groups and SAP HANA primary resource group. Support for SAP HANA on RHEL PowerHA SystemMirror on Linux Smart Assist application supports making SAP HANA highly aailable on RHEL for the SAP solutions. Support for LDAP PowerHA SystemMirror supports OpenLDAP to manage LDAP users and user groups across all PowerHA SystemMirror clusters. For using OpenLDAP with PowerHA SystemMirror, the following prerequisites are required: OpenLDAP Serer must be installed, configured, and must be accessible from all cluster nodes. OpenLDAP Client must be installed and configured on all cluster nodes. PowerHA SystemMirror user groups proide an additional leel of security and enable the system administrators to change the configuration settings of a group of users as a single entity. Users and user groups can be managed by using the clmgr command from any node in a cluster. The clmgr command sends new and updated information to all of the other nodes in the cluster. Support for file system on shared storage PowerHA SystemMirror supports both the ext3 and xfs type of file systems. PowerHA SystemMirror allows to add or delete a file system in PowerHA SystemMirror or system configuration and resource group. The resource group that consist of only file systems as resources supports startup policy to come online on any node in the node list and does not support fallback policy. Support for resource group reset In case one or more resources in a resource group are in error state (FAILED OFFLINE or STUCK ONLINE), PowerHA SystemMirror on Linux allows to reset all concerned resources currently in error state within same resource group by using the clmgr command to reset a specific resource group. The resource group must be reset only after the actual issue leading to resource being in an error state is fixed or resoled by user or concerned technical expert. Support to resource group deletion forcefully In case a resource group is stuck in a situation where it cannot be deleted automatically then PowerHA SystemMirror allows to delete it forcefully. The deletion of resource group forcefully is not recommended because if any resources in that resource group (such as an application or serice_ip) are in error state STUCK ONLINE then those are deleted with exception of file system. Updated erification checks for cluster PowerHA SystemMirrorPowerHA SystemMirror for Linux erification process runs the following check: Specific PowerHA SystemMirror modifications to the Linux system files are correct. Copyright IBM Corp. 2017,

10 The cluster and the corresponding resources are configured correctly. Security is configured correctly. All nodes agree on the cluster topology, network configuration, and the ownership and takeoer of PowerHA SystemMirror resources. The following new checks (in addition to existing ones) introduced in the erification for PowerHA SystemMirror for Linux: Verify the aailability of the logical olumes on all cluster nodes. If the file system is mounted, erify the size of logical olumes to know that how much of the logical olume free. Verify whether the same disk is part of multiple file system resources to gie an appropriate warning. Verify the aailability of olume groups on all cluster nodes. Verify the size of logical olumes on all the cluster nodes. Support for fully qualified domain name (FQDN) PowerHA SystemMirror on Linux accepts either the FQDN or corresponding short name as parameter alue for node name in any of the create or add command. The node name that is shown in output of any PowerHA SystemMirror command other than any add operation like add cluster or add node would be the short name only. This is alid in case where the cluster nodes are able to correctly resole the related node name. If the clmgr command is not able to correctly resole the node name to IP, it aborts the add node or add cluster operation. The node name that is displayed in any further PowerHA SystemMirror commands would be the short name only. The node name in any further PowerHA SystemMirror add commands like add resource group or add interface can be either FQDN or the short name. Support for Japanese language translation PowerHA SystemMirror on Linux support for Japanese language enables users to be able to interact with the software when the language set on their system is Japanese. To set language the user can export the LC_ALL ariable by using the following command: export LC_ALL=Ja_JP PowerHA SystemMirror GUI The PowerHA SystemMirror GUI SP 1 proides the following features: GUI installation Simplified installation procedure by making the post-install configuration step as an optional step. Cluster monitoring and management Performs actions of deletion of node, resource group, or resources (file system, application, serice IP). Displays the details of resource group and the respectie resource in the View section. Improed and aligned Linux cluster eents. Resource group actions Create resource such as file system in the cluster from the PowerHA SystemMirror GUI. Resources Displays the details of file system, serice IPs, and application associated to resource group. User management Enhancements to support responsie UI and accessibility improements. 2 IBM PowerHA SystemMirror for Linux Version 7.2.2: Release Notes

11 Log management Improed the accessibility. Role management Manage permissions set in the built-in roles with detailed description on permission. About Section Introduced GUI ersioning in the About window of PowerHA SystemMirror GUI. Cluster monitoring and management Ability to remoe cluster from UI iew (cluster is not deleted on the backend) and ability to discoer cluster by using the remote key. User management Added a new Manage GUI permission that is named for access control Manage Clusters option now supports the Create and Delete actions Renamed Define zones option to Manage zones option, which is more accurate and consistent with the other permissions.

14 6 IBM PowerHA SystemMirror for Linux Version 7.2.2: Release Notes

15 Installation For information about installing PowerHA SystemMirror for Linux, see the Installing PowerHA SystemMirror Version for Linux topic. Note: If you are on PowerHA SystemMirror Version for Linux, uninstall this older ersion to install PowerHA SystemMirror for Linux Version Serice Pack 1 as support for migration from PowerHA SystemMirror on Linux to future releases is proided starting with PowerHA SystemMirror for Linux Version Serice Pack 1. For information about installing PowerHA SystemMirror graphical user interface (GUI) Version Serice Pack 1, see the Installing PowerHA SystemMirror GUI topic. The PowerHA SystemMirror graphical user interface (GUI) has the following limitations in the PowerHA SystemMirror for Linux Version Serice Pack 1: If you cannot add or create a cluster, erify that the SSH connection from the PowerHA SystemMirror graphical user interface (GUI) serer system to the remote system is working, and does not prompt you for a response. For example: # ssh /bin/hostname The authenticity of host ' ( )' can't be established. ECDSA key fingerprint is 41:19:ea:f6:4f:46:91:29:f5:a0:fd:89:91:f7:28:97. Are you sure you want to continue connecting (yes/no)? In the current ersion of the PowerHA SystemMirror graphical user interface (GUI), you must respond to the prompt to establish the SSH connection. You must respond by entering yes to add the host to the ~/.ssh/known_hosts file of the PowerHA SystemMirror graphical user interface (GUI) serer. Verify that SSH must be configured to allow root access to add existing clusters to the GUI, or create new cluster through the GUI. The SSH configuration setting is PermitRootLogin yes in the /etc/ssh/sshd_config file. You must restart the SSH serice. If SSH configuration is not allowing password authentication so either change the SSH config PasswordAuthentication yes in the /etc/ssh/sshd_config file and restart the SSH serice or authenticate by using the SSH key. In PowerHA SystemMirror graphical user interface (GUI), you cannot change the host name of any managed cluster node. If you must change the host name of a cluster node that the PowerHA SystemMirror graphical user interface (GUI) serer is managing, you might need to remoe the cluster from the PowerHA SystemMirror graphical user interface (GUI) serer before you change the host name, then add the cluster again after you change the host name. Once you perform this step a single time, you will not hae to repeat it for eery connection. In PowerHA SystemMirror graphical user interface (GUI), you cannot change the host name of the GUI serer host. If you must change the host name of the GUI serer, you must either remoe all your clusters, rediscoer them after you change the host name, or manually update the /usr/es/sbin/cluster/ui/agent/configurationagent.json file on eery cluster node and replace the old serer IP address with the new address in the serer URL. Restart the agent after this update is complete. You need a root user ID to create or add a cluster. After the cluster is added to the PowerHA SystemMirror graphical user interface (GUI), a root user ID is no longer required to manage it. If you create a cluster by using the PowerHA SystemMirror graphical user interface (GUI) wizard, you cannot configure an alternate node name or a persistent IP for the first node that you added to the cluster. The first node is used to authenticate to the remote enironment. It is included in the cluster with a default node label that is assigned to it. Copyright IBM Corp. 2017,

16 The option to authenticate by using an SSH key is not aailable from the open terminal feature. SSH authentication is now supported only by password. 8 IBM PowerHA SystemMirror for Linux Version 7.2.2: Release Notes
